Watch it double.
Duckweed is one of the fastest-growing plants on Earth. On our raceways a covered surface doubles in two to three days. Tap the water to drop in a few fronds, then harvest the way we do: take most of the mat and leave enough to regrow.

Sped up about 100,000 times. Each doubling stands for about two and a half days.
Pakistan imported more than two million tonnes of soybeans in 2024–25, most of it for animal feed, all of it paid for in dollars before it reaches a single pond. Duckweed grows right here, on water, and doubles in days.

From pond to pellet

Grow
Duckweed spreads across shallow raceways lined with black HDPE. A paddlewheel keeps the water moving and a solar borewell keeps it topped up.
2–3 days

Harvest
We harvest straight off the surface, check every pond for pH, temperature, colour and pests, and let the mat grow back.
Again and again
we skim the mat and leave enough to regrow
-
Dry
Fresh duckweed is about 90% water. Drying it locks the protein into a meal that keeps and travels.
Up to 40%

Rohu that grew fifteen-fold on duckweed.
Rohu stocked at about 100 g in our duckweed ponds reached up to 1.5 kg in roughly four months, and silver carp went from 20 g to 800 g. We didn't buy a single bag of feed for them.
Seen on our own ponds near Islamabad.
